Represents a SVG 'svg' element. An SVG document fragment consists of any number of SVG elements contained within an ‘svg’ element. The TSVGDocument class represents the actual SVG.

The TSVGDocument class is the base class for parsing a SVG and generating TSVGxxxElement classes to describe the SVG. Use the TSVGDocument class to load an SVG and paint the SVG to a TCanvas.

noteNote

The TSVGDocument is only available at run-time. The TRSSVGDocument (VCL) and TRSFMXSVGDocument (FMX) expose the TSVGDocument for loading at design-time.

Matches(String)

Returns the specificity (>=0) of the match with the selector string or -1 if there is no match.

A selector's specificity is calculated as follows:

1. Count the number of ID selectors in the selector (= a)
2. Count the number of class selectors, attributes selectors, and pseudo-classes in the selector (= b)
3. Count the number of type selectors and pseudo-elements in the selector (= c)
4. Ignore the universal selector
5. Selectors inside the negation pseudo-class are counted like any other, but the negation itself does not count as a pseudo-class.




























































Concatenating the three numbers a-b-c (in a number system with a large base) gives the specificity.
